Warhol’s 300 drawings from the 1950s, about to be published as a book, are, says Mark Brown, ‘a revelation…They show another side to Warhol, an artist we mostly know for his pop-art screen prints, his soup cans, car crashes, Marilyns and so on.’ (Anyone who reduces Warhol to those few things doesn’t know much about Warhol.) ‘Here,’ continues Brown, ‘we see a skilled and sensitive draughtsman producing images that are more Egon Schiele than pop art.’
